I am unable to use breakpoints or the debugger in cs50's codespace

Body

I'm very new to coding, only on week 2 of cs50's intro to computer science. I had no idea that the debugger or breakpoints exist until week 2's lecture went over it. The lecture also introduced arrays and to familiarize myself with them I tried to do some of the practice problems, and try to debug with a actually debugger instead of printf. But they do not show up on the left of the lines of code. The allow breakpoints everywhere setting is on.

When I click on Run and Debug it says "All debug extensions are disabled. Enable a debug extension or install a new one from the Marketplace." I cannot download any extensions, and when I open the log in attempt to download one this message shows up in the output section of the Linux terminal

Also when I first boot up the codespace, it displays this in the output section of the Linux terminal

In the output section of the Linux terminal there is a drop-down menu on the right side next to the "clear output" button, which has a bunch of lines and an x in the shape of a flag. In the drop-down menu there are a lot of things to select that changes what the output displays. When I select "Tasks", the output displays this.

Error: there is no registered task type 'cppbuild'. Did you miss installing an extension that provides a corresponding task provider?

When I looked up this error it said it has something to do with the debugger so I thought this would be good to put in this. I've looked and looked for discussion posts that have had the same problem I'm having and I cannot find any. I would not be surprised if the issue was very simple as I am new to coding. I tried doing a post on stack overflow but it got downvoted 3 times and went away because I put a picture of the problem I was having. Thank you to anyone that reads this.
